,Application niednovember en, 1925*.ser'iai Ne. raam-5 4 f 1- In; ,thewinding; of yarn, packages, more particularly inthe form of yarnVcheeses,

which are cross wound and thereforeof a soft naturein the compact woundform, a

central tube or holder is provided on which theyarn is wound. Vhen'itAis desired to Vdye such'a cheese in the wound form, by the vpassing ofsuch fluids through the yarn mass, it has been hitherto necessary toremove such central tube, and afterwards replacev it or insert in thecentral bore which it occupieda holder vof some other stiff inaterial.The weight'and cost ofthetube or other holder adds considerably to thecost of the 4yarn in handling and shipment, with the addition of thecost of shipment of thetubes or holders back tothe source, when thecheeses have been wound off by the purf chaser. The percentageof1 wasteof these tubes or holders is also high. l

rlhe function of these tubes whenreim sertedfin cheeses is topreventfthecheese bore vfrom closing` with kresultant stabbing of theyinner coils ofthe windings whenA the cheese is placedon a. spindle forwindingv 013, My present invention has for .object a ineans for keepingthe boreofa cheese open to prevent possible Ydamage to the inner yarnwindings without the use of stiff tubes lor the like', with a minimum ofcost, the weight. added to each cheese being inlinitesimal-` Accordingto the said invention I provide al perfectlyflexible tube-which may beplaced upon .a spindle andr thecheese Wound there-` upon, `or theftubevmay be inserted in 'tlie cheese bore at any pointinthe treatment of thesaid cheese, if the latter hasv been wound upon a stiffl tube or thelike, after the re` 1 moval of the latter. The cheeses may there` forebe packed closeflyyforV shipment, some compression of thesaidcheeses-being permissible, and the presencev of the flexible holderin the boreof each ensures that at any timegeach cheese-may be placedupon a spindlefor winding off or any'other treatment without danger ofsuch 'spindle becoi'ning entangledfwith the inner yarn `windings,

"thus stabbing andspoiling the cheese.,
